What is the Difference Between PL-SQL and T-SQL?

PL-SQL and T-SQL are both procedural extensions of SQL, which is the standard language for dealing with relational databases. They are used to interact with database servers and perform various operations, but they have some differences:

1. Developer: PL-SQL is developed by Oracle, while T-SQL is developed by Microsoft.
2. Compatibility: PL-SQL performs best with Oracle database servers, while T-SQL performs best with Microsoft SQL servers.
3. Subquery Requirement: In T-SQL, both the DELETE and UPDATE statements are improved to enable data from another table to be used in the operations without using a subquery. In PL-SQL, a subquery is needed to use data from another table in the operation.
4. Bulk Insert: T-SQL allows inserting multiple rows into a table using the BULK INSERT statement, while PL-SQL does not have this feature.
5. Object-Oriented Programming (OOP): PL-SQL supports OOP concepts like data encapsulation, function overloading, and information hiding, while T-SQL does not.
6. Insertion: In T-SQL, the SELECT INTO statement is used, while the INSERT INTO statement must be used in PL-SQL.

In summary, PL-SQL and T-SQL are both procedural extensions of SQL, but they are developed by different companies and have different features and compatibilities. PL-SQL is used primarily with Oracle database servers, while T-SQL is used with Microsoft SQL servers.

Comparative Table: PL-SQL vs T-SQL

Here is a table comparing the differences between PL-SQL and T-SQL:

PL-SQL is an extension of SQL language developed by Oracle, which combines the data manipulation power of SQL with procedural features of programming languages. On the other hand, T-SQL is an extension of SQL language developed by Microsoft, which is considered to perform best with Microsoft SQL servers.
